I am in contact with the Cardano community, is there any news about its integration with ICP?
Yes, they have been joining at steady rate the ICP army.
Have no worries they are welcome and can still integrate our ranks in 8 years.
I was also part of the Cardano community and 4 years ago I abandoned everything for ICP but I think there can be friendly solutions for everyone and I hope so.
Cardona is supported thanks to ECDSA, so you are welcome to create CARDANO RPC or ckCARDANO
